Crack Width and Crack Spacing In Reinforced Concrete Members

ACI Journal Proceedings, 1965
A SIMPLE METHOD IS DEVELOPED FOR CALUCLATION OF CRACK WIDTH AND CRACK SPACING IN REINFORCED CONCRETE MEMBERS. THE CRACK WIDTHS DETERMINED BY THIS METHOD WERE COMPARED WITH TEST DATA OBTAINED FROM FLEXURAL AND TENSILE MEMBERS REINFORCED WITH ONE BAR. THE SHAPE OF THE MAIN CRACKS WAS INVESTIGATED BY MEANS OF SHORT TENSION MEMBERS OF A LENGTH EQUAL TO THE

Cracking and Crack Width Patterns in Large Masonry Beams

ACI Structural Journal, 2014
Earlier studies on large reinforced concrete (RC) beams found that the width of side-face cracks can be larger than the width of cracks at the extreme tension face. Accordingly, many RC design standards and codes recommend using skin reinforcement to limit the width of side-face cracks.

The Algorithm to Measure Crack Width with Incircle

Advanced Materials Research, 2013
Crack is a major defect of buildings. Digital image methods are often used to detect cracks. But incorrect or un-unique results may be inverted with an inappropriate algorithm. An image processing way is presented to obtain the sole width value. Meanwhile, the crack with several branches can be measured.

Finite width effects in a cracked plate

International Journal of Fracture, 1976
The expression for the strain energy of a plate with an elliptical hole has been derived using the Inglis solution, in an attempt to trace the missing details between the Griffith Solutions of 1921 and 1924. The results obtained permit, to a first approximation, the evaluation of the finite width effect on the stress-intensity factor of a cracked plate.

Crack width for thick offshore plates

Materials and Structures, 2011
Using thick concrete covers in offshore and nuclear containment applications is increasing because it is a durability issue. Most crack width models indicate that increasing concrete covers results in increased crack spacing and hence increased crack width this means that thick concrete covers are detrimental to crack control. In this paper, tests were

Corrosion in cracked and uncracked concrete – influence of crack width, concrete quality and crack reopening

Magazine of Concrete Research, 2010
Cracks influence the durability of reinforced concrete (RC) structures in aggressive environments by accelerating the ingress of corrosive agents to the embedded steel. This study investigated the influence of crack width (0·7 mm, 0·4 mm and incipient cracks), binder type (100% CEM I (ordinary Portland cement – OPC) and 50/50 OPC/Corex slag blend ...

Crack Width Evaluation of Reinforced Concrete Membrane Elements

Structural Engineering International, 2009
The design methods developed over the last few decades to describe the behaviour of two-dimensional reinforced concrete elements subjected to in-plane loading do not permit a simplified assessment of crack opening: some of these methods, in fact, permit this assessment but are difficult to use for practical design purposes, whereas others, instead, can

Impact of crack width on bond: confined and unconfined rebar

Materials and Structures, 2010
This paper reports the results of a research project comparing the effect of surface crack width and degree of corrosion on the bond strength of confined and unconfined deformed 12 and 16 mm mild steel reinforcing bars. The corrosion was induced by chloride contamination of the concrete and an applied DC current.

Numerical Model for Crack Width Calculation in Concrete Elements

Structural Engineering International, 2006
The paper presents engineering numerical model for crack width calculation in conventional reinforced, prestressed and composite concrete elements exposed to bending. Cross section can be of an arbitrary shape, with an arbitrary position of reinforcement and eccentric external force. It can also be made composite in several phases.

Crack spacing and crack width investigation from experimental CRCP sections

International Journal of Pavement Engineering, 2006
Crack width (CW) and crack spacing (CS) data from full-scale continuously reinforced concrete pavement (CRCP) test sections were collected and analyzed for this study. In order to compare CWs obtained under different temperature conditions, the CRCP CW model presented in the new mechanistic–empirical pavement design guide (MEPDG) was utilized to ...
